The global automotive emergency braking system market is projected to grow from USD 36.86 billion in 2025 to USD 75.99 billion by 2035, registering a CAGR of 7.5% during the forecast period. This growth is being driven by widespread deployment of advanced driver assistance systems (ADAS), rising regulatory mandates, and heightened public focus on vehicle safety.
In April 2024, the USA National Highway Traffic Safety Administration (NHTSA) finalized Federal Motor Vehicle Safety Standard No. 127, which mandates automatic emergency braking (AEB) systems on all new passenger vehicles and light trucks by 2029. These systems must be capable of stopping vehicles traveling at speeds up to 62 mph and must recognize pedestrians in both daytime and nighttime conditions. NHTSA confirmed that crash prevention is expected to be significantly enhanced through early intervention braking technologies.
Complementing the regulatory push, the USA Department of Transportation, in collaboration with MITRE’s PARTS initiative, released new data in early 2025 on AEB system effectiveness. The report concluded that AEB systems reduced rear-end collisions involving passenger vehicles by approximately 49%. These findings have reinforced global initiatives to adopt forward-collision warning and automatic braking systems across mid-segment models.

According to a 2024 report by Wired, recent advancements in radar and camera fusion have allowed emergency braking systems to function more reliably at highway speeds and in low-visibility environments. Multi-sensor integration and improved real-time data processing have made AEB more responsive, even in multi-vehicle traffic scenarios.
OEMs have accelerated the rollout of AEB systems as standard features. High-speed emergency braking is now being embedded into EV platforms and crossovers to comply with Euro NCAP and NHTSA ratings. According to Reuters, nearly all vehicles sold in the USA will require AEB by 2029 under the finalized rule, impacting both domestic and international automakers.
As ADAS adoption grows and sensor costs decline, AEB systems are expected to become ubiquitous across vehicle categories, playing a pivotal role in minimizing road accidents and achieving Vision Zero safety goals globally.
Fusion technology accounted for 36% of the global market share in 2025 and is projected to grow at a CAGR of 7.9% through 2035. The adoption of fusion systems was driven by the need to combine data from radar, cameras, and LiDAR to improve detection accuracy and decision-making in emergency braking scenarios.
In 2025, OEMs implemented fusion-based platforms in vehicles equipped with Level 2 and Level 2+ ADAS capabilities to enhance object recognition, eliminate blind zones, and reduce false positives. Fusion-enabled braking systems were prioritized in markets like Japan, Germany, and the USA, where active safety regulations were expanded.
Automakers partnered with Tier-1 suppliers to develop custom fusion algorithms capable of real-time data interpretation across multiple driving conditions. Fusion technology was also scaled to mid-range vehicles, aided by chipset cost optimization and increased processing power.
Forward emergency braking held 58% of the global application share in 2025 and is expected to grow at a CAGR of 7.6% through 2035. This application was integrated as a core ADAS feature across new vehicle models to comply with safety mandates and reduce frontal collision risks. In 2025, regulatory frameworks such as UNECE Regulation No. 152 in Europe and voluntary AEB adoption programs in the USA supported forward emergency braking implementation in both ICE and electric vehicles.
Sensor arrays-primarily radar and camera-based-were calibrated to detect vehicles, pedestrians, and cyclists in urban and highway scenarios. OEMs deployed forward emergency braking systems in compact cars, crossovers, and premium SUVs, making it one of the most widely adopted active safety functions. System refinements included dynamic braking pressure adjustment and adaptive responsiveness based on speed and obstacle proximity.
Challenges
High Implementation Costs and Technical Complexities
High technological costs of advanced sensor technologies are limiting the growth of the AEBS market, which includes radar, LiDAR, and camera-based systems. This cost limitation restricts the penetration of AEBS into affordable and entry-level cars. Moreover, the integration of AEBS into existing vehicle architectures creates technical challenges, as it necessitates the upgrading of vehicle control systems and sensor networks by automakers.
In addition, false braking activates a safety condition by environmental and road conditions and sensor calibration issues that leads to consumer hesitancy. The need for accurate threat detection and to avoid unnecessary braking continues to be a key challenge for AEBS manufacturers.
Opportunities
Regulatory Push and Increasing Adoption in Commercial Vehicles
However, the implementation of AEBS is being driven by government mandates and safety regulations, especially in North America and Europe. The National Highway Traffic Safety Administration (NHTSA) and European Commission are implementing stricter safety regulations, making it mandatory for new vehicles to have automatic braking systems.
Further, the growing penetration of AEBS in commercial fleets and heavy-duty trucks is also expected to create high growth opportunity. Rising adoption of AEBS by logistics and transport firms to mitigate the risk of accidents and meet safety regulations is contributing to market growth.
The automotive emergency braking system market will be cross-functional in nature, covering varied industrial needs related to electric and autonomous; the demand for electric and autonomous vehicles is on the rise, owing to the continuous efforts of governments across the globe to put regulations in place for safer driving.
The vast adoption of automatic emergency braking (AEB) is ramping up, thanks to new mandates from the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) requiring the technology in every new vehicle by 2029 - and speeding the expansion to passenger cars, SUVs and commercial fleets.
As automotive manufacturers like Tesla, General Motors, and Ford push radar- and camera-supported AEB systems into their latest vehicles, lead demand for such advanced sensor, LiDAR, and AI-enhanced braking will grow. Smart city growth, 5G connectivity, and vehicle-to-everything (V2X) communication are also improving the capabilities of emergency braking systems through real-time data sharing about on-road vehicles, obstacles, and traffic compatibility.
Increasing concerns about pedestrian and cyclist safety in urban settings also are helping spur adoption of upgraded automatic braking technologies. The aftermarket sector is booming in the USA, too, as more consumers are retrofitting collision avoidance systems on older cars to improve safety.
